First off, let's find the ones that are NOT true. Then we'll be left with some choices. :-) 

Which one do you think is NOT true? :)

anonymous · Answer

B and C

anonymous · Answer

And I do believe that it is A.

jabez177 · Answer

Carbon (C) has 15 known isotopes, from 8C to 22C, 2 of which (12C and 13C) are stable. The longest-lived radioisotope is 14C, with a half-life of 5,700 years. This is also the only carbon radioisotope found in nature—trace quantities are formed cosmogenically by the reaction 14N + 1n → 14C + 1H. The most stable artificial radioisotope is 11C, which has a half-life of 20.334 minutes. All other radioisotopes have half-lives under 20 seconds, most less than 200 milliseconds. The least stable isotope is 8C, with a half-life of 2.0 x 10−21 s. Averaging over natural abundances, the relative atomic mass for carbon is 12.0107(8). https://en.wikipedia.org/wiki/Isotopes_of_carbon

Do you have a conflict? :)

anonymous · Answer

Oh yah! Hey, would you mind helping me with a few more? And what's a conflict? (Also I will write you a testimony)

jabez177 · Answer

Um, I can definitely try. :) 
A conflict is something that will come in between. So in the terms as we were talking up there, it means, "Do you have a different say or do you agree with the answer?" type of way. :p

jabez177 · Answer

And thank you! :)

anonymous · Answer

Oh okay. I do agree with the answer. :D
